Definition and Usage
The border-image-slice property specifies how to slice the image specified by border-image-source. The image is always sliced into nine sections: four corners, four edges and the middle.
The "middle" part is treated as fully transparent, unless the fill keyword is set.
Tip: Also look at the border-image property (a shorthand property for setting all the border-image-* properties).
